My cocker Tessa has one of those under her eye - she's aging and it just came out last year - the vet said it's nothing to worry about - but if you feel concern - have your vet take a look at him..... and way to go saving that babies life....it sounds like you're doing the best you can and if you can get the fleas under control you'll really be doing well. We use Frontline and have only seen ONE flea - and I freaked when I saw it - then also - Heartguard too - ALWAYS - even in the winter here because of the mosquitos |
